Find the mean, median, and mode of the following list of values. round to the nearest tenth if necessary. 18, 7, 40, 23, 29, 30, 7, 7 a. mean = 20.1 median = 20.5 mode = 7 c. mean = 20.1 median = 23 mode = 7 b. mean = 20.1 median = 20.5 mode = 40 d. mean = 80.5 median = 20.5 mode = 7

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
